HENRY H. ASHLOCK, OF SAN DIEGO, CALIFORNIA.

OIL-BURNER.

Application filed. January 4, 1919.

To all whom it may concern Be it known that I, HENRY H. ASI-ILOOK, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Oil-Burners, of which the following is aspecification.

My invention relates to improvements in oil burners particularly for use in connection with cooking and heating. stoves, ranges, boilers, furnaces, fire-places. and the like more particularly to that class of burner which utilizes crude oil or stove distillate and steam in combination as a fuel and the objects of my invention are, first, to improve the general form and construction of oil burners over my patent for oil burners issued in the United States Patent Ofiice, No vember 27, 1917, Patent Number 1,248,055; second, to provide an oil burner in which the steam is produced and superheated by the burner for aiding, in the fuel combustion and distribution of the heat; third, to provide a burner of this class with means for catching the scale from the inside of the large pipe and preventing its going through the small steam pipe to the nozzle thus preventing its clogging at the nozzle; fourth, to provide a burner of this classwith means in connection therewith for conducting: and, distributing the flame for fireplace purposes and fifth, to provide an oil burner of this class which is simple. and economicalof construction, durable, easy to ignite, easy to operate and will not readily deteriorate or get out of order.

With these and other objects in. view as will appear hereinafter, my invention consists of certain novel features of construction, combination, and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appendedclaims, reference being had to the accompanying drawings and to the characters of reference thereon which form a art of this application in which:

igure 1 is a side elevational. view of my burner in the preferred form showing portions broken away and in section to facilitate the illustration; Fig. 2 is a top or plan view thereof ,Fig. Sis-a. sectional view looking upwardly, through 83 of Fig. 1; Fi 4: is a longitudinal sectional view throng Specification of Letters Patent.

the middle thereof of a modified form of the burner; Fig. 5 is a transverse sectional View thereof through 5-5 of Fig. 41; Fig. 6 is a.

top or plan view of a modified form of" the burner adapted for use in a fire-place and Fig. 7 is a longitudinal sectional. view The pan 1 is shallow and elongatedin, shape tapering backwardly on its top edge.

and it is provided with an enlarged portion 1 which is offset sidewise and upwardly and it is also provided with a central tapering rib 1 dividing the pan into two chambers one of which is a generating, chamber 2. It is also provided with another partition 1" which extends from the outside in a diagonal direction to the rib 1" which is for the purpose of guiding and directing oil to the generating chamber 2 and the rib 1 is provided with a low portion 1 adapted to permit the oil to run over. The outward end of this rib is also very low permitting passage of the oil over the end of the ribat. the outward end. The inner surfaceof the pan and ribs are covered with a layer of fire clay or paste 3, to prevent overheatingand warping the iron. Mounted over the generating chamber 2 is a Water pipe 4 the one end of which communicates with any desired water, supply and extends downwardly through the plate 8 and over said generating chamber and communicates at the outer end of the pan 1 with one end of a steam dome 5 which is arranged outside. of the end of said pan 1. This dome 5 is cylindrical, in form and one end of the steam pipe 6 communicates with the other end thereof and the opposite end of said steam pipe 6 extends backwardly just outside of the pan 1 past the middle of said plate 8 andthere is formed a loop in the end beneath theplate 8. The extended end of said steam pipe 6 is flattened forming passes through the water pipe lto the steam dome 5 then the steam dome 5 further heats and superheats the same and it passes in its superheated state through the pipe 6 and through said nozzle 6 The one end of the oil pipe 7 extends in a vertical position so that its end is adjacent to and just over said nozzle. These pipes 4t and 6 are non-corrosive wrought iron pipes to prevent corrosion when not in use. This oil supply pipe 7 extends upwardly through the plate 8 and to any oil supply reservoir as desired. This plate 8 is separate from the pan and slants slightly toward the dome to permit oil or other accumulations to run toward the generating pan and it is provided with holes 8 for air inlets.

In the modified form of construction shown in Figs. 4, 5 and 6 of the drawings the pan is of slightly different shape and extends straight back on both sides instead of being offset sidewise and it is provided with a hood 9 instead of the upwardly offset portion and the plate 8, and the pan is provided. with a pair of tapering ribs 1 which vanish toward the outer end upon which is loosely mounted an inclined generating plate 2 which is provided around its outer edge with the flange 2 adapted to prevent the oil from running off at the edge.

On top of this inclined plate 2 in the pan 1 is heaped a mass of broken pieces of fire brick and mounted over said pieces of fire brick are the water pipe 4 and steam pipe 6; otherwise, the construction is the same.

In Figs. 6 and 7 is shown a cover plate 10 which is adapted to rest against the hood 9 or on the portion 1 in the preferred form and extend over the'pan 1, pipes at and 6 and steam dome 5 for confining the blaze to a certain position for use in a fire-place. It is provided with a loose plate 10 adapted to be removed when desired which plate is provided with a plurality of perforations 10 and with a cutaway portion 10 adapted to permit the blaze to rise from said cover in the back portion of the fire-place thus making the burner applicable for use in a firelace.

p Though I have shown and described a particular construction, combination, and arrangement of parts and portions and certain modified forms thereof I do not wish to be limited to this particular construction, and these modifications but desire to include in the purview of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction there is provided an oil burner which produces steam from the water and uses the same in connection with the oil for fuel and also for spraying or spreading the oil at the point of ignition to provide proper combustion and distribution of the heat; that the steam dome superheats the steam and also provides; a means for catching the scale from the pipe 4 and also regulates the steam making the pressure uniform; that the fire clay or paste or pieces of fire brick protect the surface of the iron and prevent its becoming overheated and warping; that the cover for the end of the burner provides a means to be used in connection therewith making it applicable for fire-place use; that the steam and oil in the proper regulated quantities will provide a fuel that Will produce a maximum of efficiency and a minimum of carbon and soot; that the pipes being non-corrosive wrought iron will not corrode when the burner is not in use.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a device of the class described, a generating pan, means for preventing said pan from overheating, a small steam generating pipe extending longitudinally over said pan, a large superheating steam dome mounted in close proximity to the end of said pan with which the one end of said pipe communicates intermediate its sides, a small steam conducting pipe communicating with the other end of said steam dome intermediate its sides and extending above said pan forming a loop and flattened at the end forming a spray nozzle, a fuel oil conducting pipe with its outlet positioned immediately in front of and above the nozzle of said steam conducting pipe and means for regulating the proportionate quantities of fuel oil and water to said burner.

.2. In a device of the class described, a generating pan, means for preventing said pan from overheating, a small steam generating pipe extending longitudinally over said pan, a large superheating steam dome mounted in close proximity to the end of said pan with which the one end of said pipe communicates intermediate its sides, a small steam conducting pipe communicating with the other end of said steam dome intermediate its sides and extending above said pan forming a loop and flattened at the end forming a spraying nozzle, a fuel oil conducting pipe with its outlet positioned immediately in front of and above the nozzle of said steam conducting pipe, means for regulating the proportionate quantities of fuel, oil and water to said burner, and means for conducting fuel oil to the generating pan under said steam pipe.

3, In a device of the class described, the

combination of a pan provided with an inclined generating plate therein, a water conducting pipe extending over said plate, a steam dome with which said water pipe communicates resting against the end of said pan, a steam pipe communicating with said steam dome and extending over said plate forming a loop and having a nozzle at the one end thereof, a fuel oil conducting pipe With its outlet positioned immediately in front of and above the nozzle of said steam conducting pipe and means for covering the inwardly extending end of said burner com prising a casing with its Walls diverging backwardly and provided with a plurality of perforations therein.

In testimony whereof, I have hereunto set 10 my hand at San Diego, California, this 27th day of December, 1918.
